Abstract

The antiviral activity of an extract mixture from Celosia cristata and Raphanus sativus was tested against viral hemorrhagic septicemia virus (VHSV). Pretreatment of EPC cells with this extract up to 72 h before VHSV infection markedly reduced the virus titer, but it had no effect when added after virus inoculation. In olive flounder that received 5 µg of extract per fish, Mx expression peaked at 48 h after treatment. In contrast, ISG15 and TLR2 expression peaked at 72 h, and that of TLR7 peaked at 48 h, followed by a slight decrease at 72 h, indicating that the antiviral activity was mediated by induction of gene expression involved in the innate immune response.
